Honestly this is sort of a loaded question. Crane Gold has a few different rocker designs.

The earlier ones had a very small trunnion slot and very few tower nuts worked with them with out serious interference.

You will have to get the measurements and verify. I really want to say they will not work, but without knowing which series rockers you have and the nut body dimensions, it would just be a WAG.

Good luck.

If the thrust end of the lock fits into the counterbore in the trunion and clears the rocker itself (throughout the full range of motion of the rocker...while using the correct length pushrod) then they'll work fine.  I've had to machine down the OD of a few polylocks that interfered.
